Inventors regularly sign over their inventions to the businesses that they work for, such that the businessmen are able to make business models out of them that the engineers will scale. To be honest, I don't think you know much of how the patent system works to substantiate your comment.
Not to mention, inventions occur in manufacturing, distribution, marketing, and business too. Just because someone doesn’t have an understanding of how things work is not a justification to be dismissive.
